Improvement in
water-wheels



UNITED STATES PATENT OEEICE(l .NELSON JOHNSON, OF RATHBONEVILLE, NEW YORK.

IMPROVEMENT IN WATER-WH EELS.

Specification forming part of Letters Patent No. 3,510, dated March 26,

To all whom it may concern:

Be it known that I, NELSON JOHNSON, of Rathboneville, Steuben county, State of New York, have invented a new and useful Improvement in the Construction of Tater- Wheels, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure l is a top View. Fig. 2 is a side View. Fig. 3 is a vertical section. Fig. 4 is a view of the bottom.

The following description relates to a reaction Wheel turning horizontally, the shaft be` ing Vertical in a direction contrary to that in which the water escapes. The wheel, however, will act as well in a vertical position, the shaft being horizontal.

The wheel consists of a horizontal circular plate A, having a perforation B in the center for the shaft, called the eye of the wheel, around the outer circumference of which are a number of tapering spherical buckets O at an angle of about forty-tive degrees, overlapping each other at the several outlets, united at their-upper edges to a circular rim D, scalloped onits inner circumference, corresponding with the curvature of the upper edges of lthe buckets, which are attached to the rim of the scalloped portion thereof, said rim flaring' downward and outward at an angle of about thirty degrees with a horizontal plane. The buckets taper gradually from the points D2 of the scalloped rim nearest the center of the Wheel to the points D3 of the scallops farthest from the center of the wheel. The concave spherical form of the buckets is extended into the circular plate by scallopiug the plate in segments, spiral grooves E extending along thelower or bottom edges of the buckets from the outer lower corners of the buckets, where they intersect the outer circumference of the circular plate, to the inner circumference of the plate. t

The object of tapering the aforesaid hollow spherical buckets is to increase the pressure of the water at the outlets or discharging apertures or issues for the Wat-er, causing the wheel to run with greater power than the ordinary WheeLvWit-h buckets enlarged at the outlets or tapering in a reverse manner. V

The tapering form of the buckets is obtained by the use of the aforesaid hollow frustuin-of-a-cone rim scalloped in the manner described.

What I claim as my invention, and which I desire to secure by Letters Patent, is-

The combination of the aforesaid scalloped hollow frustum-of-a-cone rim D with the spherical tapered buckets C and scalloped plate A, in the manner and for the purpose set forth.

NELSON JOHNSON.
